Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473958, here are decompositions:
- 37 + 2147473921 = 2147473958
- 61 + 2147473897 = 2147473958
- 67 + 2147473891 = 2147473958
- 109 + 2147473849 = 2147473958
- 379 + 2147473579 = 2147473958
- 607 + 2147473351 = 2147473958
- 661 + 2147473297 = 2147473958
- 691 + 2147473267 = 2147473958
Showing the first eight; more decompositions exist.
